BASIS OF PRESENTATION	'
BASIS OF PRESENTATION	'
	NOTE 1—BASIS OF PRESENTATION
	PacWest Bancorp is a bank holding company registered under the Bank Holding Company Act of 1956, as amended. Our principal business is to serve as the holding company for our Los Angeles-based wholly-owned banking subsidiary, Pacific Western Bank, which we refer to as "Pacific Western" or the "Bank." When we say "we," "our," or the "Company," we mean the Company on a consolidated basis with the Bank. When we refer to "PacWest" or to the holding company, we are referring to the parent company on a stand-alone basis.
	Pacific Western is a full-service commercial bank offering a broad range of banking products and services including: accepting demand, money market, and time deposits; originating loans and leases, including commercial, real estate construction, equipment finance leases, SBA guaranteed and consumer loans; and providing other business-oriented products. Our operations are primarily located in Southern California extending from San Diego County to California's Central Coast; we also operate three banking offices in the San Francisco Bay area, a leasing operation based in Utah, and asset-based lending operations based in Arizona as well as San Jose and Santa Monica, California. The Bank focuses on conducting business with small to medium sized businesses in our marketplace and the owners and employees of those businesses. The majority of our loans are secured by the real estate collateral of such businesses. Our asset-based lending function operates in Arizona, California, Texas, Colorado, Minnesota, and the Pacific Northwest. Our equipment leasing function has lease receivables in 45 states.
	We generate our revenue primarily from interest received on loans and leases and, to a lesser extent, from interest received on investment securities, and fees received in connection with deposit services, extending credit and other services offered, including foreign exchange services. Our major operating expenses are the interest paid by the Bank on deposits and borrowings, compensation and general operating expenses. The Bank relies on a foundation of locally generated and relationship-based deposits, with 73 branches located across 10 California counties. The Bank has a relatively low cost of funds due to a high percentage of noninterest-bearing and low cost deposits.
	We have completed 26 acquisitions from May 2000 through March 31, 2014, including the acquisition of First California Financial Group, Inc. ("FCAL") on May 31, 2013. Since 2000, our acquisitions have been accounted for using the acquisition method of accounting and accordingly, the operating results of the acquired entities have been included in the condensed consolidated financial statements from their respective acquisition dates. See Note 3, Acquisitions, for more information about the FCAL acquisition, and Note 18, Subsequent Events, for information regarding the completion of the CapitalSource Inc. ("CapitalSource") merger on April 7, 2014.
	Basis of Presentation
	The accounting and reporting policies of the Company are in accordance with U.S. generally accepted accounting principles, which we may refer to as GAAP. All significant intercompany balances and transactions have been eliminated.
	Our financial statements reflect all adjustments that are, in the opinion of management, necessary to present a fair statement of the results for the interim periods presented. Certain information and note disclosures normally included in consolidated financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission. The interim operating results are not necessarily indicative of operating results for the full year.
	Use of Estimates
	Management of the Company has made a number of estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period to prepare these condensed consolidated financial statements in conformity with GAAP. Actual results could differ from those estimates. Material estimates subject to change in the near term include, among other items, the allowance for credit losses, the carrying value of intangible assets, the carrying value of the FDIC loss sharing asset, the realization of deferred tax assets, and the fair value estimates of assets acquired and liabilities assumed in acquisitions.
	Reclassifications
	Certain prior period amounts have been reclassified to conform to the current period's presentation format. Starting with the June 30, 2013 quarter-end, loan tables present non-purchased credit impaired ("Non-PCI") and purchased credit impaired ("PCI") loan categories in addition to covered and non-covered loan information. Previously the loan tables only presented covered and non-covered loan categories.

	NOTE 2—DISCONTINUED OPERATIONS
	In connection with the acquisition of FCAL on May 31, 2013, we acquired Electronic Payment Services ("EPS"), a division of the Bank that is being discontinued. Accordingly, all income and expense related to EPS have been removed from continuing operations and are included in the condensed consolidated statements of earnings under the caption "Loss from discontinued operations." For the three months ended March 31, 2014, revenues (net interest income plus noninterest income) and pre-tax loss for the EPS division were $3,000 and $1.4 million, respectively. Liabilities of the EPS division, which consist primarily of noninterest-bearing deposits, are included in the condensed consolidated balance sheets under the caption "Discontinued operations." For segment reporting purposes, the EPS division is included in our Banking Segment.

	First California Financial Group Acquisition
	On May 31, 2013, we completed the acquisition of First California Financial Group, Inc., or FCAL. As part of the acquisition, First California Bank or FCB, a wholly-owned subsidiary of FCAL, merged with and into Pacific Western.
	In the FCAL acquisition, each share of FCAL common stock was converted into the right to receive 0.2966 of a share of PacWest common stock. The exchange ratio was calculated based on the volume-weighted average share price of PacWest common stock for the 20 consecutive trading days ending on the second full trading day prior to the receipt of the last of the regulatory approvals required under the merger agreement. PacWest issued an aggregate of approximately 8.4 million shares of PacWest common stock to FCAL stockholders. In addition, 1,094,000 shares of FCAL common stock previously owned by PacWest at a cost of $4.1 million were cancelled in the transaction. These shares were carried in our securities available-for-sale portfolio at their estimated market value with their unrealized gain of $5.2 million included in stockholders' equity at May 31, 2013. Under acquisition accounting, this unrealized gain was recognized in earnings. Based on the closing price of PacWest's common stock on May 31, 2013 of $28.83 per share, the aggregate consideration paid to FCAL common stockholders, including the 1,094,000 shares of FCAL common stock owned by us and cancelled in the merger, was $251.6 million.
	The FCAL acquisition has been accounted for under the acquisition method of accounting. The assets and liabilities, both tangible and intangible, were recorded at their estimated fair values as of the May 31, 2013 acquisition date. The application of the acquisition method of accounting resulted in goodwill of $129.1 million. All of the recognized goodwill is expected to be non-deductible for tax purposes.
	FCB was a full-service commercial bank headquartered in Westlake Village, California. FCB provided a full range of banking services, including revolving lines of credit, term loans, commercial real estate loans, construction loans, consumer loans and home equity loans to individuals, professionals, and small to mid-sized businesses. FCB operated 15 branches throughout Southern California in the Los Angeles, Orange, Riverside, San Bernardino, San Diego, Ventura, and San Luis Obispo Counties. We made this acquisition to expand our presence in Southern California. We completed the conversion and integration of the FCB branches to Pacific Western's operating platform in June 2013 and as a result, we added seven locations to our branch network.
	See Note 18, Subsequent Events, for information regarding the completion of the CapitalSource Inc. merger on April 7, 2014.

GOODWILL AND OTHER INTANGIBLE ASSETS	'
GOODWILL AND OTHER INTANGIBLE ASSETS	'
	NOTE 4—GOODWILL AND OTHER INTANGIBLE ASSETS
	Goodwill arises from the acquisition method of accounting for business combinations and represents the excess of the purchase price over the fair value of the net assets and other identifiable intangible assets acquired. Goodwill and other intangible assets deemed to have indefinite lives generated from purchase business combinations are not subject to amortization and are instead tested for impairment no less than annually. Impairment exists when the carrying value of goodwill exceeds its implied fair value. An impairment loss would be recognized in an amount equal to that excess and would be included in "Noninterest expense" in the condensed consolidated statement of earnings.
	Our intangible assets with definite lives are core deposit intangibles, or CDI, and customer relationship intangibles, or CRI. These intangible assets are amortized over their respective estimated useful lives to their estimated residual values and reviewed for impairment at least quarterly. The amortization expense represents the estimated decline in the value of the underlying deposits or loan customers acquired. The weighted average amortization period remaining for our CDI and CRI was 2.6 years. The aggregate CDI and CRI amortization expense is expected to be $5.3 million for 2014. The estimated aggregate amortization expense related to these intangible assets for each of the next five years is $4.8 million for 2015, $3.0 million for 2016, $1.6 million for 2017, $1.3 million for 2018, and $954,000 for 2019.
	The following table presents the changes in the gross amounts of CDI and CRI and the related accumulated amortization for the periods indicated:

	The covered private label collateralized mortgage obligations ("CMO's") were acquired in the FDIC-assisted acquisition of Affinity Bank in August 2009 and are covered by an FDIC loss sharing agreement. The loss sharing provisions of this agreement expire in the third quarter of 2014 for non-single family covered assets such as these private label CMO's. Other securities consist primarily of asset-backed securities. See Note 11, Fair Value Measurements, for information on fair value measurements and methodology.
	As of March 31, 2014, securities available-for-sale with a carrying value of $291.9 million were pledged as collateral for borrowings, public deposits and other purposes as required by various statutes and agreements.
	During the three months ended March 31, 2014, we sold $137.3 million in government-sponsored enterprise ("GSE") pass through securities for which we realized a gross gain of $4.8 million. We sold these securities to take advantage of favorable market conditions for premium coupon seasoned GSE pass through securities, and redeployed the proceeds into single-maturity investments that are expected to perform better under current market conditions. During the three months ended March 31, 2013, we sold $12.4 million in corporate debt securities for which we realized a $409,000 gross gain. These securities were sold as part of our investment portfolio risk management activities to reduce price volatility and duration.

We reviewed the securities that were in a continuous loss position less than 12 months and longer than 12 months at March 31, 2014, and concluded that their losses were a result of the level of market interest rates relative to the types of securities and pricing changes caused by shifting supply and demand dynamics and not a result of downgraded credit ratings or other indicators of deterioration of the underlying issuers' ability to repay. Accordingly, we determined that the securities were temporarily impaired and we did not recognize such impairment in the condensed consolidated statements of earnings. Additionally, we have no plans to sell these securities and believe that it is more likely than not we would not be required to sell these securities before recovery of their amortized cost.
The following table presents the contractual maturity distribution of our available-for-sale securities portfolio based on amortized cost and carrying value as of the date indicated:

Mortgage-backed securities have contractual terms to maturity, but require periodic payments to reduce principal. In addition, expected maturities may differ from contractual maturities because obligors and/or issuers may have the right to call or prepay obligations with or without call or prepayment penalties.

FHLB Stock
At March 31, 2014, the Company had a $25.0 million investment in Federal Home Loan Bank of San Francisco ("FHLB") stock carried at cost. During the first quarter of 2014, FHLB stock decreased $2.9 million due to redemptions by the FHLB. We evaluated the carrying value of our FHLB stock investment at March 31, 2014, and determined that it was not impaired. Our evaluation considered the long-term nature of the investment, the current financial and liquidity position of the FHLB, repurchase activity of excess stock by the FHLB at its carrying value, the return on the investment, and our intent and ability to hold this investment for a period of time sufficient to recover our recorded investment.

LOANS AND LEASES	'
	NOTE 6—LOANS AND LEASES
	The Company's loan portfolio consists of (1) purchased credit-impaired ("PCI") loans and (2) non-purchased credit-impaired ("Non-PCI") loans. PCI loans represent acquired loans for which there was, at the acquisition date, evidence of credit deterioration since their origination and it was probable that we would be unable to collect all contractually required payments. Such loans are accounted for in accordance with ASC Subtopic 310-30, "Loans and Debt Securities Acquired with Deteriorated Credit Quality." Non-PCI loans are comprised of originated loans and acquired non-impaired loans for which there was no evidence of credit deterioration at their acquisition date and it was probable that we would be able to collect all contractually required payments. Originated loans are carried at the principal amount outstanding, net of unearned income. Unearned income is recognized as an adjustment to interest income over the contractual life of the loans using the effective interest method or taken into income when the related loans are paid off or sold. The purchase discount on acquired non-impaired loans is recognized as an adjustment to interest income over the contractual life of such loans using the effective interest method or taken into income when the related loans are paid off or sold.
	We further present our loans by "covered" and "non-covered" loan categories. Covered loans represent loans covered by loss sharing agreements with the FDIC for which we will be reimbursed for a substantial portion of any future losses under the terms of the agreements. Covered loans also include a portion of the loans acquired in the FCAL acquisition as FCB had acquired two failed banks from the FDIC for which the loss sharing agreements with the FDIC remain in effect. Non-covered loans and leases represent loans and leases not covered by FDIC loss sharing agreements.

In addition to our internal risk rating process, our federal and state banking regulators, as an integral part of their examination process, periodically review the Company's loan risk rating classifications. Our regulators may require the Company to recognize rating downgrades based on their judgments related to information available to them at the time of their examinations. Risk rating downgrades generally result in higher allowances for credit losses.

	Total borrowings	$	5,748					$	113,726
	The non-recourse debt represents the payment stream of certain leases sold to third parties. The debt is secured by the equipment in the leases and all interest rates are fixed. As of March 31, 2014, this debt had a weighted average remaining maturity of 2.2 years.
	The Bank has established secured and unsecured lines of credit. We may borrow funds from time to time on a term or overnight basis from the FHLB, the Federal Reserve Bank of San Francisco ("FRBSF"), or other financial institutions.
	FHLB Secured Lines of Credit.    The borrowing arrangements with the FHLB are based on two separate FHLB programs, one collateralized by loans and the other by securities available-for-sale. At March 31, 2014, our FHLB borrowing lines were secured by: (1) a blanket lien on certain qualifying loans in our loan portfolio which were not pledged to the FRBSF, and (2) available-for-sale securities with a carrying value of $10.7 million. As of March 31, 2014, our aggregate remaining borrowing capacity under the FHLB secured borrowing lines was $1.3 billion.
	FRBSF Secured Line of Credit.    The Bank has a secured line of credit with the FRBSF. As of March 31, 2014, the Bank had secured borrowing capacity of $580.7 million collateralized by liens covering $722.8 million of certain qualifying loans. As of March 31, 2014 and December 31, 2013, there were no balances outstanding.
	Federal Funds Arrangements with Commercial Banks.    As of March 31, 2014, the Bank had unsecured lines of credit of $80.0 million with correspondent banks for the purchase of overnight funds, subject to availability of funds. These lines are renewable annually and have no unused commitment fees. As of March 31, 2014 and December 31, 2013, there were no balances outstanding.

	Interest payments made by the Company on subordinated debentures are considered dividend payments under the Board of Governors of the Federal Reserve System ("FRB") regulations. Bank holding companies, such as PacWest Bancorp, are required to notify the FRB prior to declaring and paying a dividend to stockholders during any period in which quarterly and/or cumulative twelve-month net earnings are insufficient to fund the dividend amount, among other requirements.
	Brokered Deposits
	Brokered time deposits totaled $48.0 million at March 31, 2014, and $49.4 million at December 31, 2013, all of which were part of the CDARS program. The CDARS program represents deposits that are participated with other FDIC-insured financial institutions as a means to provide FDIC deposit insurance coverage for the full amount of our customers' deposits.

COMMITMENTS AND CONTINGENCIES	'
	NOTE 10—COMMITMENTS AND CONTINGENCIES
	Lending Commitments
	The Bank is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit, standby letters of credit, and commitments to purchase equipment being acquired for lease to others. Those instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the condensed consolidated balance sheets. The contract or notional amounts of those instruments reflect the extent of involvement the Company has in particular classes of financial instruments.
	The following table presents a summary of the financial instruments described above as of the dates indicated:
		March 31,		December 31,
		2014		2013
		(In thousands)
	Loan commitments to extend credit	$	1,010,073	$	1,001,740
	Standby letters of credit		35,125		39,200
	Commitments to purchase equipment being acquired for lease to others		17,262		8,475
		$	1,062,460	$	1,049,415
	Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements.
	Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support private borrowing arrangements. Most guarantees expire within one year from the date of issuance. The Company generally requires collateral or other security to support financial instruments with credit risk.
	In addition, the Company has investments in low income housing project partnerships, which provide the Company income tax credits, and in a few small business investment companies. The investments call for capital contributions up to an amount specified in the partnership agreements. As of March 31, 2014 and December 31, 2013, the Company had commitments to contribute capital to these entities totaling $16.8 million and $11.0 million, respectively.
	Legal Matters
	In the ordinary course of our business, we are party to various legal actions, which we believe are incidental to the operation of our business. The outcome of such legal actions and the timing of ultimate resolution are inherently difficult to predict. In the opinion of management, based upon information currently available to us, any resulting liability, in addition to amounts already accrued, taking into consideration insurance which may be applicable, would not have a material adverse effect on the Company's financial statements or operations.
	FCAL-Related Litigation
	As set forth below, there are a number of litigation matters pending against FCB, the defense of which PacWest has assumed.
	Fourteen lawsuits have been filed in the Superior Court of the State of California, County of Los Angeles against FCB, among others, by various former clients of political campaign and non-profit organization treasurer Kinde Durkee. The lawsuits are entitled (i) Wardlaw, et al. v. First California Bank, et al. (Case No. SC 114232), filed September 23, 2011; (ii) Lou Correa for State Senate, Orange County's Youth et al. v. First California Bank, et al. (Case No. BC 479872), filed February 29, 2012; (iii) Committee(s) to Re-elect Lorreta Sanchez, Linda Sanchez, and Susan Davis, et al. v. First California Bank, et al. (Case No. BC 479873), filed February 29, 2012; (iv) Holden for Assembly v. First California Bank, et al. (Case No. BC 489604), filed August 3, 2012; (v) Latino Diabetes Ass'n v. First California Bank, et al. (Case No. BC 489605), filed August 3, 2012; (vi) Jose Solorio Assembly Officeholder Committee, et al. v. First California Bank, et al. (Case No. 492855), filed September 27, 2012; (vii) Foster for Treasurer 2014, et al. v. First California Bank, et al. (Case No. BC 492878), filed September 27, 2012; (viii) Los Angeles County Democratic Central Committee, et al. v. First California Bank, et al. (Case No. BC 492854), filed September 27, 2012; (ix) FCAL v. 68th AD Democratic PAC, et al. (Case No. : BC470812), filed September 23, 2011(the "Interpleader Action"); (x) First California Bank v. Shallman, John, Shallman Communication/John D. Shallman v. FCB (Case No. LC099226), filed December 11, 2012; (xi) National Popular Vote, et al. v. First California Bank, et al. (Case No. BC501213) filed February 19, 2013; (xii) Zine v. First California Bank, et al. (Case No. BC504476), filed April 2, 2013; (xiii) Rothman, Elliott v. FCAL (Case No. BC511180), filed June 5, 2013; and (xiv) Ted Lieu as Treasurer for Ted Lieu for Assembly 2008 v. First California Bank (Case No. BC470182), filed November 18, 2011.
	Plaintiffs in each of the cases claim, among other things, that FCB aided and abetted a fraud and unlawful conversion by Ms. Durkee and/or her affiliated company of funds held in accounts at FCB. Based largely on the same alleged conduct, plaintiffs also assert claims for an alleged violation of California Business & Professions Code Section 17200 and for declaratory relief. Plaintiffs seek compensatory and punitive damages, as well as various forms of equitable and declaratory relief.
	Each of the cases is pending before the same judge, who is coordinating their progress. FCB has answered each of the complaints, and the parties have engaged in discovery.
	On September 23, 2011, FCB filed a Complaint-in-Interpleader in the Superior Court of the State of California, County of Los Angeles (Case No. BC 470182), pursuant to which FCB interpleaded the sum of $2,539,049 as the amounts on deposit in accounts at FCB that were controlled by Ms. Durkee on behalf of the several hundred named defendants (the "Interpleader Action"). FCB seeks an order requiring the defendants to interplead and litigate their respective claims, discharging FCB from liability, and restraining proceedings or actions against FCB by the defendants with respect to those amounts. On December 6, 2011, the Interpleader Action was designated as complex and transferred to the Superior Court's complex litigation division. It has been related to the other pending actions that relate to the conduct of Ms. Durkee.
	On June 18, 2012, FCB moved for summary judgment in the Interpleader Action. At hearings held in late 2012 and early 2013, the Superior Court entered summary judgment with respect to a majority of the accounts at issue. Those sums have been paid by the Superior Court to the former accountholders. There still remains a total of $99,884.79 on deposit with the Court in the Interpleader Action.
	In September 2013, Ms. Durkee pled guilty to mail fraud resulting in a judgment of $9.7 million being entered against her. The parties participated in a mediation on October 16, 2013, which did not result in settlement of any claims. Thereafter, at a Further Status Conference on December 19, 2013, the Court scheduled a jury trial on August 13, 2014 as to the following cases: Orange County's Youth, Latino Diabetes Association, Jose Solorio Assembly Officeholder Committee, Holden for Assembly, and Committee(s) to Re-elect Lorreta Sanchez, Linda Sanchez, and Susan Davis (the "First 7 Plaintiffs"). July 14, 2014 has been reserved as the hearing date for the Bank's motion for summary judgment on the claims of the First 7 Plaintiffs.
	CapitalSource Merger-Related Litigation
	Since July 24, 2013, 11 putative stockholder class action lawsuits (the "Merger Litigations") were filed against PacWest and certain other defendants in connection with PacWest entering into the CapitalSource Merger Agreement in which PacWest agreed to acquire CapitalSource. The CapitalSource Merger Agreement was publicly announced on July 22, 2013. Five of the 11 actions were filed in Superior Court of California, Los Angeles County: (1) Engel v. CapitalSource, Inc. et al., Case No. BC516267, filed on July 24, 2013; (2) Miller v. Fremder et al., Case No. BC516590, filed on July 29, 2013; (3) Basu v. CapitalSource, Inc. et al., Case No. BC516775, filed on July 31, 2013; (4) Holliday v. PacWest Bancorp et al., Case No. BC517209, filed on August 5, 2013 and (5) Iron Workers Mid-South Pension Fund v. CapitalSource Inc. et al., Case No. BC517698, filed on August 8, 2013 (collectively, the "California Actions"). The other six actions were filed in the Court of Chancery of the State of Delaware: (1) Fosket v. Byrnes et al., Case No. 8765, filed on August 1, 2013; (2) Bennett v. CapitalSource, Inc. et al., Case No. 8770, filed on August 2, 2013; (3) Chalfant v. CapitalSource et al., Case No. 8777, filed on August 6, 2013; (4) Oliveira v. CapitalSource, Inc. et al., Case No. 8779, filed on August 7, 2013; (5) Desai v. CapitalSource, Inc. et al., Case No. 8804, filed on August 13, 2013; and (6) Fattore v. CapitalSource, Inc. et al., Case No. 8927, filed on September 19, 2013 (collectively, the "Delaware Actions").
	On August 15, 2013, the Delaware Actions were consolidated into a single action, captioned In re CapitalSource Inc. Stockholder Litigation, Consol. C.A. No. 8765-CS, and assigned to Chancellor Leo E. Strine. On September 25, 2013, plaintiffs in the Delaware Actions filed a Verified Consolidated Amended Class Action Complaint (the "Delaware Consolidated Complaint"). On September 17, 2013, the California Actions were consolidated into a single action, captioned In re CapitalSource Inc. Shareholder Litigation, Lead Case No. BC516267, and assigned to Judge Elihu M. Berle. On October 2, 2013, plaintiffs in the California Actions filed an Amended Consolidated Complaint (the "California Consolidated Complaint").
	The Delaware Consolidated Complaint and the California Consolidated Complaint each allege that the members of the CapitalSource board of directors breached their fiduciary duties to CapitalSource stockholders by approving the proposed merger for inadequate consideration; approving the transaction in order to obtain benefits not equally shared by other CapitalSource stockholders; entering into the merger agreement containing preclusive deal protection devices; and failing to take steps to maximize the value to be paid to the CapitalSource stockholders. The Delaware Consolidated Complaint and the California Consolidated Complaint also each allege claims against CapitalSource and PacWest for aiding and abetting these alleged breaches of fiduciary duties. Plaintiffs in these actions seek, among other things, declaratory and injunctive relief concerning the alleged breaches of fiduciary duties, injunctive relief prohibiting consummation of the merger, rescission, an accounting by defendants, damages and attorneys' fees and costs, and other and further relief. The judge in the Delaware Actions ruled on October 23, 2013, that discovery would proceed in the Delaware Actions and that it would be shared with the plaintiffs in the California Actions and that the California Actions would be stayed while that process takes place. Thereafter, on October 28, 2013, the California Actions' plaintiffs stipulated in the California Actions that they would participate in the discovery process in the Delaware Actions and the administrative stay in the California Actions will remain in place unless and until the Delaware Actions are abandoned.
	On December 20, 2013, the parties in the California and Delaware Actions entered into a Memorandum of Understanding (the "MOU") setting forth the terms of an agreement in principle to settle both the California and Delaware Actions, subject to certain conditions and future occurrences. Under the terms of the MOU, the merger closed on April 7, 2014. The parties are finalizing a draft Stipulation of Settlement which, consistent with the terms of the MOU, will resolve both the California and Delaware Actions. The parties plan to submit this Settlement Stipulation to the Delaware Court for review as soon as it is complete, and to seek Court approval shortly thereafter. There is also a further status conference scheduled in the California Action on September 10, 2014. At this stage, it is not possible to predict the outcome of the proceedings or their financial impact on the Company; however, the agreements provide, among other things, for payment of Plaintiffs' attorneys fees by Company and/or its insurers, as a condition precedent to a release and dismissal of the Merger Litigations with prejudice.

FAIR VALUE MEASUREMENTS	'
	NOTE 11—FAIR VALUE MEASUREMENTS
	We use fair value to measure certain assets on a recurring basis, primarily securities available-for-sale; we have no liabilities being measured at fair value. For assets measured at the lower of cost or fair value, the fair value measurement criteria may or may not be met during a reporting period and such measurements are therefore considered "nonrecurring" for purposes of disclosing our fair value measurements. Fair value is used on a nonrecurring basis to adjust carrying values for impaired loans and other real estate owned and also to record impairment on certain assets, such as goodwill, core deposit intangibles, and other long-lived assets.
	The following table presents information on the assets measured and recorded at fair value on a recurring basis as of the date indicated:

The following is a description of the valuation methodologies used to measure our assets recorded at fair value (under ASC Topic 820, "Fair Value Measurement") and for estimating fair value for financial instruments not recorded at fair value (under ASC Topic 825).
Cash and due from banks.    The carrying amount is assumed to be the fair value because of the liquidity of these instruments.
Interest-earning deposits in financial institutions.    The carrying amount is assumed to be the fair value given the short-term nature of these deposits.
Securities available-for-sale.    Securities available-for-sale are measured and carried at fair value on a recurring basis. Unrealized gains and losses on available-for-sale securities are reported as a component of "Accumulated other comprehensive income" in the condensed consolidated balance sheets. See Note 5, Investment Securities, for further information on unrealized gains and losses on securities available-for-sale.
Fair value for securities categorized as Level 1, which are publicly traded securities, are based on readily available quoted prices. In determining the fair value of the securities categorized as Level 2, we obtain a report from a nationally recognized broker-dealer detailing the fair value of each investment security we hold as of each reporting date. The broker-dealer uses observable market information to value our securities, with the primary source being a nationally recognized pricing service. We review the market prices provided by the broker-dealer for our securities for reasonableness based on our understanding of the marketplace and we consider any credit issues related to the securities. As we have not made any adjustments to the market quotes provided to us and they are based on observable market data, they have been categorized as Level 2 within the fair value hierarchy.
Our covered private label CMOs are categorized as Level 3 due in part to the inactive market for such securities. There is a wide range of prices quoted for private label CMOs among independent third party pricing services and this range reflects the significant judgment being exercised over the assumptions and variables that determine the pricing of such securities. We consider this subjectivity to be a significant unobservable input and have concluded that the covered private label CMOs should be categorized as a Level 3 measured asset. Our fair value estimate was based on prices provided to us by a nationally recognized pricing service which we also use to determine the fair value of the majority of our securities portfolio. We determined the reasonableness of the fair values by reviewing assumptions at the individual security level about prepayment, default expectations, estimated severity loss factors, and discount rates, all of which are not directly observable in the market. Significant changes in default expectations, severity loss factors, or discount rates, which occur all together or in isolation, would result in different fair value measurements.
FHLB stock.    Investments in FHLB stock are recorded at cost and measured for impairment quarterly. Ownership of FHLB stock is restricted to member banks and the securities do not have a readily determinable market value. Purchases and sales of these securities are at par value with the issuer. The fair value of investments in FHLB stock is equal to the carrying amount.
Non-PCI impaired loans.    Nonaccrual loans and performing restructured loans are considered impaired for reporting purposes and are measured and recorded at fair value on a non-recurring basis. Non-PCI nonaccrual loans with an unpaid principal balance over $250,000 and all performing restructured loans are reviewed individually for the amount of impairment, if any. Non-PCI nonaccrual loans with an unpaid principal balance of $250,000 or less are evaluated for impairment collectively.
To the extent a loan is collateral dependent, we measure such impaired loan based on the estimated fair value of the underlying collateral. The fair value of each loan's collateral is generally based on estimated market prices from an independently prepared appraisal, which is then adjusted for the cost related to liquidating such collateral; such valuation inputs result in a nonrecurring fair value measurement that is categorized as a Level 2 measurement. The Level 2 measurement is based on appraisals obtained within the last 12 months and for which a charge-off was recognized or a change in the specific valuation allowance was made during the three months ended March 31, 2014.
When adjustments are made to an appraised value to reflect various factors such as the age of the appraisal or known changes in the market or the collateral, such valuation inputs are considered unobservable and the fair value measurement is categorized as a Level 3 measurement. The impaired loans categorized as Level 3 also include unsecured loans and other secured loans whose fair values are based significantly on unobservable inputs such as the strength of a guarantor, including an SBA government guarantee, cash flows discounted at the effective loan rate, and management's judgment.
The Non-PCI impaired loan balances shown above represent those nonaccrual and restructured loans for which impairment was recognized during the three months ended March 31, 2014. The amounts shown as net losses include the impairment recognized during the three months ended March 31, 2014, for the loan balances shown. Of the $58.1 million of nonaccrual loans at March 31, 2014, none were written down to their collateral fair values through charge-offs during the quarter.
Other real estate owned.    The fair value of foreclosed real estate, both non-covered and covered, is generally based on estimated market prices from independently prepared current appraisals or negotiated sales prices with potential buyers, less estimated costs to sell; such valuation inputs result in a fair value measurement that is categorized as a Level 2 measurement on a nonrecurring basis. As a matter of policy, appraisals are required annually and may be updated more frequently as circumstances require in the opinion of management. The Level 2 measurement for OREO is based on appraisals obtained within the last 12 months and for which a write-down was recognized during the three months ended March 31, 2014.
When a current appraised value is not available or management determines the fair value of the collateral is further impaired below the appraised value as a result of known changes in the market or the collateral and there is no observable market price, such valuation inputs result in a fair value measurement that is categorized as a Level 3 measurement. To the extent a negotiated sales price or reduced listing price represents a significant discount to an observable market price, such valuation input would result in a fair value measurement that is also considered a Level 3 measurement. The OREO losses disclosed are write-downs based on either a recent appraisal obtained after foreclosure or an accepted purchase offer by an independent third party received after foreclosure.
SBA servicing asset.    In accordance with ASC Topic 860, "Transfers and Servicing," the SBA servicing asset, included in "Other assets" in the condensed consolidated balance sheets, is carried at its implied fair value. The fair value of the servicing asset is estimated by discounting future cash flows using market-based discount rates and prepayment speeds. The discount rate is based on the current U.S. Treasury yield curve, as published by the Department of the Treasury, plus a spread for the marketplace risk associated with these assets. We utilize estimated prepayment vectors using SBA prepayment information provided by Bloomberg for pools of similar assets to determine the timing of the cash flows. These nonrecurring valuation inputs are considered to be Level 3 inputs.
Deposits.    Deposits are carried at historical cost. The fair value of deposits with no stated maturity, such as noninterest-bearing demand deposits, interest checking, money market, and savings accounts, is equal to the amount payable on demand as of the balance sheet date and considered Level 2. The fair value of time deposits is based on the discounted value of contractual cash flows and considered Level 2. The discount rate is estimated using the rates currently offered for deposits of similar remaining maturities. No value has been separately assigned to the Company's long-term relationships with its deposit customers, such as a core deposit intangible.
Borrowings.    Borrowings include overnight FHLB advances and other fixed-rate term borrowings. Borrowings are carried at amortized cost. The fair value of overnight FHLB advances is equal to the carrying value and considered Level 1. The fair value of fixed-rate borrowings is calculated by discounting scheduled cash flows through the estimated maturity dates or call dates, if applicable, using estimated market discount rates that reflect current rates offered for borrowings with similar remaining maturities and characteristics and are considered Level 2.
Subordinated debentures.    Subordinated debentures are carried at amortized cost. The fair value of subordinated debentures with variable rates is determined using a market discount rate on the expected cash flows.
Commitments to extend credit.    The majority of our commitments to extend credit carry current market interest rates if converted to loans. Because these commitments are generally unassignable by either the borrower or us, they only have value to the borrower and us. The estimated fair value approximates the recorded deferred fee amounts and is excluded from the table above because it is not material.
Limitations
Fair value estimates are made at a specific point in time and are based on relevant market information and information about the financial instrument. These estimates do not reflect income taxes or any premium or discount that could result from offering for sale at one time the Company's entire holdings of a particular financial instrument. Because no market exists for a portion of the Company's financial instruments, fair value estimates are based on what management believes to be conservative judgments regarding expected future cash flows, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimated fair values are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates. Since the fair values have been estimated as of March 31, 2014, the amounts that will actually be realized or paid at settlement or maturity of the instruments could be significantly different.

STOCK COMPENSATION PLANS	'
	NOTE 13—STOCK COMPENSATION PLANS
	The Company's 2003 Stock Incentive Plan, or the 2003 Plan, permits stock based compensation awards to officers, directors, key employees and consultants. As of March 31, 2014, the 2003 Plan authorized grants of stock-based compensation instruments to purchase or issue up to 9,000,000 shares of authorized but unissued Company common stock, subject to adjustments provided by the 2003 Plan. As of March 31, 2014, there were 3,927,147 shares available for grant under the 2003 Plan. Upon consummation of the CapitalSource merger an additional 10,686,565 shares were added to the 2003 Plan. See Note 18, Subsequent Events, for information regarding the issuance of stock in connection with the CapitalSource merger, which was completed on April 7, 2014.
	Accelerated Vesting of Restricted Stock
	In December 2013, the Company accelerated the vesting of certain restricted stock awards that resulted in a pre-tax charge of $12.4 million ($12.2 million after tax). This action was taken by the Company in order to eliminate an additional $21.0 million of compensation and tax expense related to change in control payments that the Company would have otherwise incurred upon consummation of the CapitalSource merger. Such eliminated expenses relate to tax gross-up payments and the value of lost tax deductions, in each case due to the impact of Sections 280G and 4999 of the Internal Revenue Code as they apply to change in control payments that would have become payable to certain PacWest employees in conjunction with the CapitalSource merger. The restricted stock awards that were vested on an accelerated basis in 2013 would have otherwise vested upon consummation of the CapitalSource merger, and the $12.2 million after-tax charge to earnings recorded in December 2013 would have been incurred at that time.
	In April 2014, upon closing of the CapitalSource merger, 1,013,377 awarded shares of both time-based and performance-based common stock vested due to the triggering of the change of control provision contained within the 2003 Plan. We recorded a $16.8 million after-tax charge to earnings for the vesting of such shares in April 2014.
	Restricted Stock
	At March 31, 2014, there were outstanding 479,986 shares of unvested time-based restricted common stock and 607,450 shares of unvested performance-based restricted common stock. All but 40,000 awarded shares of time-based restricted common stock that were issued prior to the closing of the CapitalSource merger vested upon the closing of the CapitalSource merger. The remaining awarded shares of time-based restricted common stock vest over a service period of four years from the date of the grant. Unless defined otherwise in the award, both time-based and performance-based restricted common stock vest immediately upon a change in control of the Company as defined in the 2003 Plan or upon death of the employee.
	Compensation expense related to time-based restricted stock awards is based on the fair value of the underlying stock on the award date and is recognized over the vesting period using the straight-line method. Restricted stock amortization, excluding the accelerated vesting of restricted stock, totaled $1.6 million, $2.3 million, and $1.8 million for the three months ended March 31, 2014, December 31, 2013, and March 31, 2013, respectively. Such amounts are included in "Compensation expense" on the accompanying condensed consolidated statements of earnings. As of March 31, 2014, total unrecognized compensation cost related to unvested restricted stock was $27.4 million. At April 30, 2014, total unrecognized compensation cost related to unvested time-based restricted stock was $1.2 million.

Under ASU 2013-11, an unrecognized tax benefit should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward. However, to the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position, or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. ASU 2013-11 was effective for us on January 1, 2014 and did not have any material effect on our financial statements.
	In January 2014, the FASB issued ASU 2014-01, "Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects." ASU 2014-01 allows investors in low-income housing tax credit ("LIHTC") entities that meet certain conditions to present the net tax benefits (net of the amortization of the cost of the investment) within income tax expense. The cost of the investments that meet the conditions will be amortized in proportion to (and over the same period as) the total expected tax benefits, including tax credits and other tax benefits, as they are realized on the tax return. ASU 2014-01 is effective for us on January 1, 2015 and is to be applied retrospectively if investors elect the proportional amortization method. However, if investors have LIHTC investments accounted for under the effective yield method at adoption, they may continue to apply that method for those existing investments. Early adoption is permitted. The adoption of this standard permits expenses currently reported in noninterest expense to be reported in income tax expense. The adoption of this standard in January 2015 will not have a material impact on our financial statements, however, total noninterest expense and income tax expense will change.
	In January 2014, the FASB issued ASU 2014-04, "Receivables—Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans Upon Foreclosure." ASU 2014-04 clarifies when a creditor should reclassify mortgage loans collateralized by residential real estate from loans receivable to other real estate owned. ASU 2014-04 defines when an in-substance repossession or foreclosure has occurred and when a creditor is considered to have received physical possession of residential real estate collateralizing a mortgage loan. ASU 2014-04 is effective for us on January 1, 2015 and can be applied either prospectively or using a modified retrospective transition method, and early adoption is permitted. We are evaluating the impact this standard may have on our financial statements.

	CapitalSource Merger
	On April 7, 2014, PacWest Bancorp ("PacWest") completed the merger with CapitalSource Inc. ("CapitalSource"). The combined company is called PacWest Bancorp. As part of the merger, CapitalSource Bank, ("CSB"), a wholly-owned subsidiary of CapitalSource, merged with and into PacWest's wholly-owned banking subsidiary, Pacific Western Bank, and the combined subsidiary bank is called Pacific Western Bank. As of March 31, 2014, CapitalSource had $9.1 billion in assets.
	Upon closing, PacWest created the CapitalSource division of Pacific Western Bank. This division, which will operate under the CapitalSource name, will continue to serve businesses nationwide with a full spectrum of middle-market lending. Pacific Western Bank, through its combined network of 81 branches throughout California, will continue to serve small and medium-sized businesses with financing solutions, cash management and deposit services.
	In the merger with CapitalSource, each share of CapitalSource common stock was converted into the right to receive $2.47 in cash and 0.2837 of a share of PacWest Bancorp common stock. PacWest issued an aggregate of approximately 56.7 million shares of PacWest common stock to CapitalSource stockholders. Based on the closing price of PacWest's common stock on April 7, 2014 of $45.83 per share, the aggregate consideration paid to CapitalSource common stockholders and holders of equity awards to acquire CapitalSource common stock was approximately $3.1 billion.
	Former holders of CapitalSource common stock and equity awards to acquire CapitalSource common stock as a group received shares of PacWest common stock in the merger constituting approximately 55% of the outstanding shares of PacWest common stock immediately after the merger. As a result, holders of PacWest common stock immediately prior to the merger, as a group, own approximately 45% of the outstanding shares of the PacWest common stock immediately after the merger.
	The integration of CSB's deposit system and the conversion of CSB's branches to Pacific Western Bank's operating platform were completed over the weekend of April 12, 2014. CSB had 21 branches, 12 of which were closed in the consolidation with Pacific Western Bank at the close of business on April 11, 2014. One overlapping Pacific Western Bank branch was closed at the close of business on April 11, 2014 as well. All remaining branches re-opened on Monday April 14, 2014 as Pacific Western Bank branches.
	CSB was a commercial lender headquartered in Los Angeles, California. CSB provided financial products to small to middle market businesses nationwide and also provided depository products and services to consumers in southern and central California. CSB's loan origination efforts were conducted nationwide with offices located in Chevy Chase, Maryland; Los Angeles, California; Denver, Colorado; Chicago, Illinois; and New York, New York. As a result of the merger, we will increase our presence as a middle-market lender and increase our market share in our primary Southern California market.
	The CapitalSource merger has been accounted for under the acquisition method of accounting. The assets and liabilities, both tangible and intangible, were recorded at their estimated fair values as of the April 7, 2014 merger date. Such fair values are preliminary estimates and are subject to adjustment for up to one year after the merger date or when additional information relative to the closing date fair values becomes available and such information is considered final, whichever is earlier. While the fair values are preliminary we believe there will not be material adjustments to the amounts recorded with the exception of the acquired tax assets, which will be finalized once the final tax returns have been filed. The application of the acquisition method of accounting resulted in goodwill of $1.6 billion. All of the recognized goodwill is expected to be non-deductible for tax purposes. The assignment of goodwill to reporting segments has not yet been completed.
	The following table presents the estimated fair values of the assets acquired and liabilities assumed for CapitalSource as of April 7, 2014:

	As of April 7, 2014, the fair value of the CapitalSource Non-PCI loans acquired was $6.8 billion, the related gross contractual amount was $7.0 billion, and the estimated contractual cash flows not expected to be collected were $121.5 million.
	The following table summarizes the accretable yield on the purchased credit impaired loans acquired in the CapitalSource merger as of April 7, 2014:

	Estimated fair value of PCI loans acquired		(88,627	)
	Acquired accrued interest receivable		—
	Accretable yield	$	25,217
	On April 7, 2014, as required by the merger agreement and as described in the joint proxy statement/prospectus relating to the merger, the Board of Directors of PacWest adopted a Tax Asset Protection Plan (the "Plan"). This Plan was described in detail in the joint proxy/prospectus and is similar to the Tax Benefit Preservation Plan that CapitalSource had in place prior to the merger. The purpose of the Plan is to seek to preserve PacWest's ability to utilize net operating loss carryforwards and certain other tax assets (collectively, the "NOLs") for U.S. federal income tax purposes that PacWest and certain of its subsidiaries will continue to have after the merger. The Plan seeks to protect the ability to utilize the NOLs by mitigating the potential for an "ownership change" within the meaning of Section 382 of the Internal Revenue Code of 1986, as amended (the "Code").
	In general, an "ownership change" would occur if PacWest's "5-percent shareholders," as defined under Section 382 of the Code, collectively increase their ownership in PacWest, in relation to their respective historical low points, by more than 50 percentage points over a rolling three-year period. In general, institutional holders that file as "investment advisers" for SEC purposes, such as mutual fund companies that hold PacWest common stock on behalf of several individual mutual funds where no single fund owns five percent or more of PacWest's common stock, are typically not treated as "5-percent shareholders" for purposes of Section 382 of the Code.
	The following table presents our unaudited pro forma results of operations for the periods presented as if the CapitalSource and FCAL acquisitions had been completed on January 1, 2013. The unaudited pro forma results of operations include the historical accounts of the Company, CapitalSource, and FCAL, and pro forma adjustments as may be required, including the amortization of intangibles with definite lives and the amortization or accretion of any premiums or discounts arising from fair value adjustments for assets acquired and liabilities assumed. The unaudited pro forma information is intended for informational purposes only and is not necessarily indicative of our future operating results or operating results that would have occurred had the CapitalSource and FCAL acquisitions been completed at the beginning of 2013. No assumptions have been applied to the pro forma results of operations regarding possible revenue enhancements, expense efficiencies or asset dispositions.

BASIS OF PRESENTATION	'
Basis of Presentation	'
	Basis of Presentation
	The accounting and reporting policies of the Company are in accordance with U.S. generally accepted accounting principles, which we may refer to as GAAP. All significant intercompany balances and transactions have been eliminated.
	Our financial statements reflect all adjustments that are, in the opinion of management, necessary to present a fair statement of the results for the interim periods presented. Certain information and note disclosures normally included in consolidated financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission. The interim operating results are not necessarily indicative of operating results for the full year.
Use of Estimates	'
	Use of Estimates
	Management of the Company has made a number of estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period to prepare these condensed consolidated financial statements in conformity with GAAP. Actual results could differ from those estimates. Material estimates subject to change in the near term include, among other items, the allowance for credit losses, the carrying value of intangible assets, the carrying value of the FDIC loss sharing asset, the realization of deferred tax assets, and the fair value estimates of assets acquired and liabilities assumed in acquisitions.
Reclassifications	'
	Reclassifications
	Certain prior period amounts have been reclassified to conform to the current period's presentation format. Starting with the June 30, 2013 quarter-end, loan tables present non-purchased credit impaired ("Non-PCI") and purchased credit impaired ("PCI") loan categories in addition to covered and non-covered loan information. Previously the loan tables only presented covered and non-covered loan categories.
